“Selena enjoyed our home-made comfort food with Justin’s mom and grandparents,” server Glynnie McCauley tells HollywoodLife.com exclusively. “They came in this morning at about 10 a.m. and stayed for about an hour. Justin’s step-mom and his step-mom’s daughter Amanda, who is 23-years-old, also joined them.”

She adds, “They all got along wonderfully. Selena sat next to Justin’s grandmother and across from Justin’s mom. They all seemed really happy. Selena was so nice. She is super sweet and even posed with one of the waitresses for a photo.”

Selena, 18, is super fit, but that didn’t stop her from enjoying herself — indulging in some of Madelyn’s best food.

“Selena had the French Toast,” Glynnie says. “When Justin’s here he usually orders Poutine, which is a Canadian dish, it’s fries with gravy and cheese, and a strawberry and banana milkshake.”
